Graphical Problems With Ati Radeon Card

I downloaded the latest driver for ATI Radeon HD 4800 gfx card this week and since then the graphics in GPL hasn't worked properly. It did work perfectly before.
Now in Direct3Dv2 mode, the graphics flicker when in the race menu screen, and when I go into the car, the screen becomes totally black. I can return to the menus, but now the text has disappeared.
In OpenGLv2 mode, the graphics looks fine, but it stutters a lot and it feels like you are driving in slow motion.
All this happened when I was about to sort out the controls for the sport cars mod, so it is very frustrating!

Cheeveer, I had the exact same thing happen to me in D3D (5850 here) after installing the 10.8 drivers in august. It didn't go away with 10.9. I tried reverting to 10.7, problem persists. I'm using Driver Cleaner .NET between uninstall and install, but I think some files evade the cleanup process. OpenGL solved it for me, if you can call it that.

I'll be trying the tip on the second page of the second link recommended by ptmac3 (previous post) to see if it changes anything.

EDIT: works! installed right on top of 10.9. Apart from the flickering letters and buttons under replay and a small square mirror on the top left of the screen which I don't know where I got from, everything's fine. This sure took long for them to look into..

I have pretty much the same result. I use the Digital Display Modifier which flickers and the small mirror on the top left where the black bar should be all the way across. I did not check out replay. The instructions for the hotfix state this:

That's interesting Bernd. For now, OGLv2 works just fine. There are some limitations to it though, like not being able to use 32 bits, although I haven't retried that yet with this hotfix. And then there is the invisible blinking cursor when trying to name a replay or setup file. It's just not there. And I can't use triple buffering without seeing corruptions in the various menu screens, but who knows if triple buffering would help anything anyway. Other than those things, right now, OGLv2, for GPL, is the *hit man! I definitely can't live with the little mirror in the top left or the flickering numbers in D3Dv2.

oks, installed the hotfix, with d3d im getting flickering in menues sometimes :\. calibration box, and when you leave the track and theres the small replay window, flickers there, sometimes green gunked text aswell on driver name etc. which .dll/raster or whatever is best to use? fiddled about abit before trying to fix it, so dont know what im using now

Nothing mentioned in this thread fixed my stuttering with my ATI card. It would be fine for a lap or two, then it would start to stutter and the framerate would drop to 20fps even though 60fps was being reported.

Two things that did fix this however were:

1. Set Vertical Sync to Always On in Catalyst Control Center
2. Make sure Triple Buffering is enabled in CCC, under the OpenGL settings menu.
